The definition of simplicity was indeed cyclic. This has been changed in the
specification.
The notion of regularity is now not mentioned explicitly anymore.
The following complaint has not been handled:
[[
... each axiom in Ax of the form SubObjectPropertyOf(SUB PE) in Ax
fulfils
at least one of following conditions:
* SUB is of the form SubObjectPropertyChain(PE PE)
* SUB is of the form InverseObjectProperty(PE) and
* SUB = SPE where SPE < PE
* SUB = SubObjectPropertyChain(SPE1 ... SPEn) where n >= 2 and
SPEi < PE for 1 <= i <= n
* SUB = SubObjectPropertyChain(PE SPE1 ... SPEn) where n >= 1 and
SPEi < PE for 1 <= i <= n
* SUB = SubObjectPropertyChain(SPE1 ... SPEn PE) where n >= 1 and
SPEi < PE for 1 <= i <= n
]]
Namely, "or" is the appropriate reading: each line depends on the
structure of SUB;
that is, each property inclusion axiom can contain SUB of one of the mentioned
forms, and this SUB must satisfy the mentioned criteria.
The well-foundedness on the role hierarchy is not a problem: the number of
roles is
always finite, since the axiom closure is always finite.
